LIBERTY IVALKUP, OF RbOKFORD, ILLINOIS.

PAINT-DISTRIBUTER.

SPECIFICATION forming part of Letters Patent No. 285,325, dated September 18, 1883.

' Application filed December 6, 1882. (Model) 'T0 all whom, it may concern Be it known that I, LIBERTY WALKUP, a citizen of the United States, residing in the city of Rockford, in the county of Winnebago and State of Illinois, have invented new and useful Improvements in Paint-Distributers, of which the following is a specification.

My invention relates to machines employed to distribute pigments in the art of painting in producing likenesses of nature or-art; and its object is to improve a paint-distributing machine patented to Abner Peeler, (assignor to myself, Liberty Valkup, and Charles Walkup,) April 25, 1882, No. 256,852, to render it a more efficient machine. To this end I have arranged and constructed the machine represented in the accompanying drawings, in which- Figure l is a plan view of a machine embodying my invention. Fig. 2 is also a plan View, in which the pivoted cap of the wind- Fig. 3 is afront elevation. Fig. 4 is a rear elevation. Fig. 5 is an isometrical representation of the working parts cut on the dotted line w. Fig. 6 is a transverse vertical section on dotted line 0:. Fig. 7 is a transverse vertical section on dotted line y, and Fig. 8 is a lengthwise vertical section on dotted line 2. W

In the figures, A represents a hand-piece, produced from any suitable material and of proper or convenient size, and in this instance is provided with an arm, 13, projecting laterally from its front edge, by means of which the operator may control the movements of the machine with greater certainty. On this hand-piece the several parts of the distributer are mounted. To the rear edge and forward portion of this hand-piece is fixed a metallic plate, at, having its under portion, 1), bent at a right angle to the plate and extending outward laterally therefrom. The forward outer portion of this lateral projection is provided with a stud-journal, c, rising vertically from its upper face.

At d is represented a wind-wheel having a tubular hub, d, fitted to receive the stud-j ournal (Z in a manner to revolve freely thereon. The periphery of this wind-wheel is provided with buckets (1, adapted to receive an air-jet,

to cause it to revolve rapidly on its journalsupport. This wind-wheel d is provided near its periphery with a tubular stud, e, depending from its under side, having its tubular opening extending upward through the wheel.

At h is represented a lever of crank-arm form, having one of its ends pivoted to the bent under portion, 1), of the plate a, rearward of the wind-wheel. The free end of this lever 'is provided with a tubular stud, 13, rising from 1 joint connection therewith. The free end of this pitman lhas a pivot joint connection with the free end of the slotted link-lever k in a manner to produce a free joint connection of the parts.

At m is represented a needle having one of its ends bent at aright angle to the shaft thereof, and its bent end is placed in the slot of the link-lever, having its bent end depending therefrom and entering a slotted guide, a, which rises from the angular plate (I, extending crosswise thereof and in the lengthwise direction of the needle. This needle extends in a free manner through a vertical slot, a, formed in the vertical portion of the plate a, and it extends laterally over the depressed center of a pigment-receptacle, O. This pigment-receptacle O has a pivotal connection at n with the plate a in such a manner that it may be turned downward, as represented in the dotted lines at Fig. 3, to render it more convenient in use. The upward movement of this receptacle is limited by means of a stopstud, 0, projecting from the plate a.

At D is represented a cap employed to cover and protect the wind-wheel and the working parts of the machine. This cap has a pivotal connection at p with the plate a in such a manner as to permit it to swing upward to the po- ICO ' sition seen in Fig. 4 to expose the working parts, as in Fig. 2, for the purpose of applying, changing, adjusting, or cleaning the parts. The outer edge, 1), of this cap is turned down over the wind-wheel, producing a guard to confine the current or jet of air to the wheel. At 1) is represented a lip or arm of the cap D, bent downward over the needle, having its free end notched or forked to span the needle, and, in connection with the outward portion of the pigment-receptacle and the transverse slotted guide to the downturned end of the needle, serve to give direction to its endwise movements. By connecting this needle-guide with the cap, as above described, the guide will serve to hold and steady the needle about centrally between its two bearing-points, and cause the needle to move in a right line to produce a continuous or unbroken line in the work, to prevent an occasional course stipple being thrown from the needle, produced by an irregular motion. The guide, also by engaging the needle near its center and being made yielding and removable, provides for the needle being held with greater or less force to the receptacle, as occasion shall require, and insures a firm and steady endwise reciprocation thereof. A further advantage gained by connecting the guide with the pivoted cover is, that the same may be turned up out of the way to permit the cleaning of the receptacle.

At E is represented a stud-shaft fitted to oscillate in a bearing in the handpiece. The upper end of this stud-shaft is provided with a lever, F, by means of which the shaft may be made to oscillate in its hearing. The lower end of this stud-shaft is fitted with a crankarm, 1', which extends outward from the hand piece. The free end of this crank-arm is connected with the free end of the lower crankarm, h, by means of a connecting-bar, 1-, having its ends pivot-jointed to the crank-arms h and r. From this construction and arrangement of the parts it will be seen that by means of the lever F the parts connected therewith and with the wind-wheel can be readily changed to their dotted-line position, or to any position within the limits of the devices for varying the distance between the fulcrum or wrist-pin connection of the slotted lever and its connection with the downturned end of the needle, which action will vary the throw or endwise movement of the needle, to vary the quantity of the pigment carried by the needle in its endwise movements.

At H is represented a metallic tube fixed in position on the hand-piece, and its rear end is provided with an opening at 8.

At I is represented a flexible tube, having its end portion passed onto the end of the tube, over the side opening, 8, and its free end is designed to connect with any suitable mechanism capable of supplying a sufficient quantity of air at a pressure suffieient to give a proper movement to the parts.

At K is represented a spring-actuated thumblever, having a pivotal connection with the hand-piece, in such position thereon that its rear end will engage the flexible tube immediately over the opening in the rear end of the metallic tube in such a manner that its spring action will operate to indent the flexible tube and prevent the passage of the air-current. The free end of this thumb-lever is in such position 011 the hand-piece as to be readily en gaged by the thumb of the operator, by which to control the flow of air through the tube.

The forward portion of the metallic tube H is provided with a branch tube, t, extending horizontally rearward, and curving forward and downward in position to deliver the compressed air forced through it onto the buckets of the wind-wheel. This tube is provided with a single-way valve, i, provided with a lever, t, by means of which the valve may be ad justed to regulate the fiow of air to the wind wheel. The forward end of the metallic tube H is provided with a vertical tube, a, having its upper end closed by means of a removable plug, a, and its lower open end, a, immediately over the free end of the needle, outside of the receptacle (3, in such position that the current of air passing through the tube will force the pigment carried from the receptacle by the reciprocating movement of the needle.

In the use of my improved paint or liquid color distributer, the pigment to be employed is placed in the receptacle 0 in contact with the needle. The machine or instrument is then taken in the hand, preferably in the right hand, and the free end of .the thumb-lever is then'dcpressed by the thumb of the operator, which permits the air from the compressor to pass through the tubes, and by means of the valve in the branch tube the air-current can be properly balanced between the wheel and distributing-tube for the proper distribution of the pigment. v

The machine represented in the drawings is more especially designed for use in the right hand, but is capable of use as a left-hand machine; but, if required, the machines may be constructed as left-hand machines, in whichinstance it will only require that the parts be placed on the opposite side or edge of the handpiece.

I claim as my invention 1. The combination, with the wind-wheel and with the needle, of a slotted lever having a pivotal support, and a pitman-connection of its free end with the wind-wheel to impart a reciprocating endwise movement of' the needle, substantially as set forth.

2. The combination, with the wind-wheel and with the needle, of a slotted lever having a pitman-eonnection with the wind-wheel, and a pivotal support made adjustable to vary the stroke or endwise throw of the needle, substantially as and for the purpose set forth.
